This is a comment on an old post, but do you still have a Twiddler? I've been looking for one and I'm wondering where to get one (I heard they stopped producing them). If you know of anyone who has one they don't use anymore, I'd love to buy one. Else, I'll just end up making one from scratch with Push-button technologies.

The reason I am asking this is because I am a Cyborg Anthropologist studying Human-Computer Interaction and wearable computing. I also suffer from Carpal Tunnel and am seeking a better way in which to imput data. I'm also involved with gesture recognition technology and less invasive ways of computing. Let me know if you have any data about this.
